Charles Krauthammer blasted Republicans for a "historic" "epic fail" of a venture to repeal and replace ObamaCare.

"This is an epic fail. This is historic," Krauthammer said.

After centrist Republican Susan Collins of Maine and conservative Rand Paul of Kentucky came out against the now-former Senate repeal bill, it could not lose any more support and still pass with a vice presidential tie-breaker.

Then came similar announcements of no-votes from Sens. Jerry Moran (R-Kan.) and Mike Lee (R-Utah), effectively killing the legislation.

Krauthammer added that the new Senate plan, a straight-up repeal of ObamaCare, is a "bluff" that won't pass either.

"Once you give an entitlement... you never can retrieve it," he said.

Collins and fellow moderates Lisa Murkowski of Alaska and Shelley Moore Capito of West Virginia said they would not vote for a full repeal.
